std::memmove

From cppreference.com
Defined in header <cstring>
void* memmove( void* dest, const void* src, std::size_t count );

Copies count characters from the object pointed to by src to the object pointed to by dest. The objects may overlap: copying takes place as if the characters were copied to a temporary character array and then the characters were copied from the array to dest. If the objects are not trivially-copyable (scalars, arrays, C-style structs), the behavior is undefined.
